Title: Photoelectron spectroscopy and ab initio calculations of small Si{sub n}S{sub m}{sup −} (n = 1,2; m = 1–4) clusters

Binary cluster anions composed of silicon and sulfur elements, Si{sub n}S{sub m}{sup −} (n = 1,2; m = 1-4), were investigated by using photoelectron spectroscopy and ab initio calculations. The vertical detachment energies and the adiabatic detachment energies of these clusters were obtained from their photoelectron spectra. The electron affinity of SiS molecule is determined to be 0.477 ± 0.040 eV. The results show that the most stable structures of the anionic and neutral Si{sub n}S{sub m} (n = 1,2; m = 1-4) clusters prefer to adopt planar configurations except that the structures of Si{sub 2}S{sub 4}{sup −} and Si{sub 2}S{sub 2} are slightly bent.
